示例1: ExecuteTransaction
public void ExecuteTransaction(string connectionString)
{
using (OleDbConnection connection =
new OleDbConnection(connectionString))
{
OleDbCommand command = new OleDbCommand();
OleDbTransaction transaction = null;
// Set the Connection to the new OleDbConnection.
command.Connection = connection;
// Open the connection and execute the transaction.
try
{
connection.Open();
// Start a local transaction
transaction = connection.BeginTransaction();
// Assign transaction object for a pending local transaction.
command.Connection = connection;
command.Transaction = transaction;
// Execute the commands.
command.CommandText =
"Insert into Region (RegionID, RegionDescription) VALUES (100, 'Description')";
command.ExecuteNonQuery();
command.CommandText =
"Insert into Region (RegionID, RegionDescription) VALUES (101, 'Description')";
command.ExecuteNonQuery();
// Commit the transaction.
transaction.Commit();
Console.WriteLine("Both records are written to database.");
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
try
{
// Attempt to roll back the transaction.
transaction.Rollback();
}
catch
{
// Do nothing here; transaction is not active.
}
}
// The connection is automatically closed when the
// code exits the using block.
}
